使用laravel将数组数据(动态)传递到chart.js,此“数据:[65、59、80、0、56、55、40]”,其中包含数字应包含来自数据库的信息。
<canvas id="myChart" width="400" height="250"></canvas>
var canvas = document.getElementById('myChart');
var data = {
labels: ["January", "February", "March", "April", "May", "June", "July"],
datasets: [
{
label: "My First dataset",
fill: false,
lineTension: 0.1,
backgroundColor: "rgba(75,192,192,0.4)",
borderColor: "rgba(75,192,192,1)",
borderCapStyle: 'butt',
borderDash: [],
borderDashOffset: 0.0,
borderJoinStyle: 'miter',
pointBorderColor: "rgba(75,192,192,1)",
pointBackgroundColor: "#fff",
pointBorderWidth: 1,
pointHoverRadius: 5,
pointHoverBackgroundColor: "rgba(75,192,192,1)",
pointHoverBorderColor: "rgba(220,220,220,1)",
pointHoverBorderWidth: 2,
pointRadius: 5,
pointHitRadius: 10,
data: [65, 59, 80, 0, 56, 55, 40],
}
]
};
function adddata(){
myLineChart.data.datasets[0].data[7] = 60;
myLineChart.data.labels[7] = "Newly Added";
myLineChart.update();
}
var option = {
showLines: true
};
var myLineChart = Chart.Line(canvas,{
data:data,
options:option
});
我正在测试数据库中的数据,我知道我的数组包含数据,但是在chart.js中显示为空白
